Problems solved by technology

The mechanical properties of welded joints are significantly reduced by about 20% compared to the mechanical properties of the base material without welded joints, which can lead to joint wear or grinding accidents
Scratched or otherwise uneven belts can quickly wear down packaging such as belt dryers and cause further problems, such as with cleaning

Embodiment Construction

[0031] Figure 1a A metal strip 102 is schematically shown, said metal strip 102 consisting of a metal strip blank 10 a having the same length as the final width of the metal strip 102 . The metal strip blanks 10a are arranged next to each other and welded to one another by friction welding, so that a weld joint 11a is produced between the metal strip blanks, which weld joint extends approximately perpendicularly with respect to the longitudinal direction of the metal strip. Figure 1b Shown is a metal strip 102 manufactured from a metal strip blank 10b of approximately the same length as the final length of the metal strip, whereby the joint 11b between the blanks is approximately parallel to the longitudinal direction of the strip. The interface between the longitudinal butt ends of each metal strip blank 10b can be approximately perpendicular to the longitudinal direction of the metal strip, and the butt ends of adjacent metal strip blanks 10b are arranged to be substantial...

Abstract

The invention relates to a method for manufacturing a metal belt (102) for use in a paper / board machine or in a finishing machine. The method comprises producing a metal belt by placing side by side and / or in succession several metal belt blanks (10a; 10b; 10c) narrower than a final width of the metal belt in a number necessitated by the belt (102) of a desired width and length, and welding joints therebetween by friction welding, the joint developing a composition substantially similar to the basic material.

Description

technical field [0001] The invention relates to a method for the manufacture of a metal strip for use in a paper / board or finishing machine. Background technique [0002] Endless steel belts are used, for example, in metal belt calenders and condebelt banddryers. Currently employed metal strips include those manufactured by conventional metallurgical melting techniques and further processed by various hot and cold working methods. A typical raw material for the belt is a web of stainless steel from which a suitable endless belt can be formed by welding. The ensuing description discusses only the main aspects of the manufacturing principle of such a belt, which are quite obvious to a person skilled in the art. In conventional production, the strip manufacturing process is carried out by melting scrap metal and / or beneficiated ore and, if necessary, alloying elements, for example in an electric arc furnace. The melt is then decarburized in a reformer to obtain the desired c...
